Abstract
A writing instrument slip attachment mechanism is disclosed which prevents the clip (3) from becoming separated from the writing instrument. The clip attachment mechanism located on the writing instrument shaft (1) includes a clip (3) having a folded back base section (4); and a clip attachment section (2) having cooperatively shaped outer and inner surfaces (2A, 2B) for operatively engaging said folded back base section (4); and a cover (5) for attachment to said clip attachment to said clip attachment section (2). The base section (4) of the clip (3) is press-fitted into the outer and inner surfaces (2A, 2B) of the clip attachment (2). The cover (5) cover the press-fitted base section (4) and preferably also helps to lock the base section (4) to the clip attachment section (2), by use of co-operatively shaped convex and concave surfaces formed between the cover and clip attachment section (2).
